~~~>>>>> Hombrew Microcomputer Builder ? If you’re a homebrew Microcomputer builder/designer then this may be of interest. ~~~~I’ve talked to funkward-tech, a Chinese supplier of ICs, into selling kits of chips.. ~~~~ see : http://stores.ebay.com/P-A-Electro-Components/DIY-Homebrew-Kits-/_i.html?_f...

Seriously, if you are doing any homebrew electronics, microcomputer Projects I may be able to give (unload) some of my surplus chips .. Things I have : CPUs... Z80,6502,68008,68000 etc SRAMs, 8K,32K,128K.. EPROMS...Various VDP...V99x8, D72020 (early PC VDP), R6545 (6845 Clone0 etc CPLDs...EPM7128SLC...

I think it's supposed to replace the actual physical Floppy disk itself ? It would be connected to an FDC (floppy disc controller, uPD765 etc) via glue logic. So the system would just think it's a large floppy disc. This would have advantages in reliability, larger capacity and faster ?

6581CBM 6581 6581R3 6581R4 SID Sound Chip IC x PDIP28

Spotted these .. didn't know you could still get Commodore SID Chips ??

Not sure whether they're Genuine...?

Call him 'Mr Chips'

Dave has accumulated a small Chip Mountain CPUs (Z80,6502,68008 etc), SRAMs, EPROMs, and much more. So if you need any ICs to build your own homebrew electronics projects it might be worth asking Dave, nicely, and he may send you some.

The MD2800-D08-X DiskOnChip ( Emulates a Floppy Disk) ?? Hi. Does anyone know much about this MD2800-D08-X DiskOnChip . An IC (available in DIP32) that I'm assuming is some form of Silicon Disk that Emulates an FDC+Floppy Drive ? Datasheet : http://www.qscomp.cz/Pdf/doc_2000.pdf https://www.usbid.co...

There's a section on Dave's Website on how to upgrade an MTX500 to 64K ...?

Hi.

Is anyone interested in ZX81 Hardware building/designing and generally messing around ?? Then I'm trying to get interest in a ZX81 Homebrew DIY Microcomputer Club.. all about building designing , modifying etc the ZX81 !!
